A right triangle is a special right triangle in which one angle measures 30 degrees and the other 60 degrees The key characteristic of a right triangle is that its angles have measures of 30 degrees (π/6 rads), 60 degrees (π/3 rads) and 90 degrees (π/2 rads) The sides of a right triangle lie in the ratio 1√32A triangle is a special right triangle that contains internal angles of 30, 60, and 90 degrees Once we identify a triangle to be a 30 60 90 triangle, the values of all angles and sides can be quickly identified Imagine cutting an equilateral triangle vertically, right down the middle Each half has now become a 30 60 90 triangle• hypotenuse = long side * ;
